Specification of Letters Patent.

Patented J une 17, 1919.

Application filed my 17,1917 Serial No 181,024.

a machine gun which is extremely simple and light in construction and which may be fired rapidly under all conditions. The machine gun is provided with a double reversible barrel which may be adjusted to permit one barrel to cool while theother barrel is in use, and the rapidity of fire may be regulated by the adjustment of the. gears which connect the operating member with the load- .ing and firing mechanism. The hammer is operated by the cartridge wheel, and the cartridge wheel and the hammer are covered by a cap which may be readily removed to correct any trouble which may arise when firing the gun and also to clean the mecha nism.

Additional objects of the invention will appear in the following specification in which the preferred form'of the invention is disclosed.

In the drawings similar reference characters denote similar parts in all the views, in which Figure 1 is a side elevation of the machine gun, parts being broken away to illustrate the construction;

Fig. 2.is a sectional view on the line 22 of Fig. 3; 1

Fig. 3 is a sectional view on the line 33 of Fig. 2;

Fig. 1 is a sectional view on the line 44 of Fig. 2;

Fig. 5 is a sectional view on the line 55 of Fig. 2;

Fig. 6 is a sectional view on the line 6-6 of Fig. 2; and

Fig. 7 is a front elevationof the barrel member. 1

By referring to the drawings it will be seen that the machine gun body is provided with a base 10 having an upwardly extending lug 11 which is spaced from the sides, and from the front and from the rear of the base 10; disposed on the base 10 at the sides of the lug ll there are side plates 12 and disposed between the side plates 12 and at the rear of the lug 11 there is a block 13,

of the lug another block 14 being disposed at the front 11 and between the side plates 12. The side plates 12 are secured to the .lug 11 by means of a bolt 15,'the block 13 is secured in position between the side plates by means of bolts 16, and .the block 14 is secured between the side plates by means of bolts 17. There are :bearings 18 and 19 on the block 13 between which there is an opening 20, and there is a bearing 21 in the block 14. J ournaled in these bearings 18, 19, and 21 there is a shaft 22, a cartridge wheel 23 being disposed between the blocks 13 and 14. and being secured to the shaft 22 for rotating with the latter. The cartridge wheel 23 has radial projectlons 2 1 and 25 which are spaced apart so that when the cartridge tape 26 is disposed around the cartridge wheel 23 between the projections 24 and 25 the forward and rear ends of the cartridges will fit the spaces between the radial projections 24 and 25 in a manner readily understood.

Disposed at the rear of the cartridge'wheel and secured for rotating therewith there is a cam member 27 which is disposed for engagement with the forward end'o f a hammer 28 which is disposed in an opening 29 in the block 13. The hammer 28 has a rearwardly extending stud 30 which fits into a bearing 31'at the rear of the opening 29 and around this stud 30 there is disposed a spring 32 for holding the hammer 28 yieldingly forward. Disposed at the rear of the cartridge wheel and adjacent the cam member 27 there is a block 33 which has in its upper surface a groove 34 for receiving the firing pin 35 which extends forwardly from the hammer 28. This firing pin 35 being disposed in position to engage a cartridge which has been moved by the cartridge wheel 23 to the firing position, the cam member 27 being so adjusted relatively to the hammer 28, that the hammer 28 and with it the firing pin will be moved rearwa rdly immediately preceding the movement of the cartridge to firing position the cam permitting the hammer 28 to move forward and with it the firing pin 35 immediately on the cartridge moving to the position in which it should be fired. Disposed over the cartridge wheel 23, the block 33 and the forward portion of the hammer 28 there is a cap 36 which with the cartridge wheel. 23 forms a chamber for the cartridge which is to be fired. This cap 36 is normally held in place by a screw bolt 37 which however, may be quickly removed to correct any fault should the firing mechanism become j ammed.

Extending forwardly from the block 14' the barrel opening. 42 in the block 14 which extends from the firing position of the car'- tridge. In this way the barrel which has been fired for a period may be cooled while the second barrel is in use. When the barrel member 38 is disposed in position it is held in place by means of a stud screw 43 in addition to the bearings 18 and 19 there is another bearing 44 in the block 13 in which a shaft 45 is journaled, gearing 46 connecting the shafts 45 and 22 so that the shaft 22 may be rotated by a crank 46 on the shaft 45. It will be understood that the gears connecting-the shafts 45 and 22 may be changed as may be desired to regulate the rapidity of firing, although the crank 46 may in all cases be rotated at the same speed.

The opening 29 in the block 13 extends for a distance through the side of said block.

to permit the introduction of the hammer 28. In the cap 36 there are transverse openings 47 which are providedto assist in keeping the cap 36 cool. The barrel member 38 hastwo front sights 48', one for each of the barrels, the frontsight 48 which extends upwardly from the barrel which is in use coiiperating with a rear Sight 49, which is mounted at the rear of the block l3. 7

There are openings 50 in the side plates 12'through whichthe cartridge tape 26 mayv worm wheel 53 journaled in bearings in a bracket 54 to whichthe depending member 51 is pivoted on a transverse axis as 55.

54) The worm wheel 53 may be rotated by. the

- hand wheel 56 to elevate or depress'the gun barrel. The bracket 54 is pivoted on avertical axis to a tripod or othersupport 57 -Having thus described my invention I claim as new and desire to secure by Letters Patent:
